Camera interface
The camera interface receives data from a sensor in parallel mode (8 to 14-bits) by storing a
full line in a buffer memory, then requesting a DMA transfer or interrupting the processor.
When all the lines of a frame are transferred, a frame sync interrupt is generated.
Main features:
●
Supports both hardware synchronization (HSYNC and VSYNC signals) and embedded
synchronization (ITU656 or CSI2).
●
Data carried by the bus can be:
–
Raw Bayer10 (10-14 bits/pixel – 2 Bytes), Raw Bayer8 (8 bits/pixel – 1 Byte),
–
YCbCr400 (1 Byte/pixel – 1 Byte), YCbCr422 (4 Bytes/ 2 pixels – 2*2 Bytes),
YCbCr444 (3 Bytes/ pixel – 4 Bytes)
–
RGB444 (2 Bytes/ pixel – 2 Bytes), RGB565 (2 Bytes/ pixel – 2 Bytes),
RGB888 (3 Bytes/ pixel – 4 Bytes)
–
JPEG compressed
●
Data is stored in a 2048 x 32 buffer memory
●
The camera interface can be assigned to two different set of pins. When using data
greater than 8-bits, it is not possible to use the MII interface.
●
Max pixel clock frequency is 100 MHz
